Decent
This animation was a half good, half not-so-good. The graphics were not that great, dont get that confused with the animation (I'll explain that in a second). The graphics, well they were just circles, the guns looked traced and there was no real enviorment. The animation on the other hand was nice, it was very fluent, very smooth and in conjuction with the violence it was good. Alot of nice pans and zooms to go with it too.
The only real problem with the animation was it was pratically all Motion Tweens, dont get me wrong, the way you showed them in this flash is as if you've mastered them. But really put some effort into some frame by frame and you could be getting a much higher score... it would make this flash look more clean and alot more exciting than a little circle going nuts.
The song was good, but im not really basing the score around what music you choose for a random killing. The style of the animation was nothing new, something just goes nuts and kills everything, meets a big bad guy... alot of mess... madness holds copyright on it pratically.
I liked the bloodsplatters, they were decent at times. But I think with your style of direction and effort in your animation that you could go for something more than just a circle making some kills for no reason. Think of a storyline, a good one and try to tell us something and excite us.
Best of luck.
